A woman presented with ingestion of multiple cylindrical batteries, which resulted in severe gastric ulcerations and erosions caused by the corrosive alkaline within 12 hours. We propose that cylindrical batteries should be removed endoscopically as soon as possible after ingestion.

An 87-year-old man presented with an actively bleeding diverticula in the sigmoid colon, for which two resolution clips were placed. After an episode of re-bleeding, an over-the-scope-clip deployed over the diverticulum and the previously placed clips, with full hemostasis.

A 15-year-old female with no past medical history presented 3 hours after ingesting 2 Buckyballs she had been using to create a mock tongue piercing. Multiple diagnostic modalities were used to find the Buckyballs before they were finally recovered via laparoscopic appendectomy.

Gastric volvulus combined with herniation of the colon is an extremely rare finding. The classic triad of retching, severe and con-stant epigastric pain, and difficulty in inserting a nasogastric tube suggests an acute gastric volvulus.

A man in his fourth decade with familial adenomatous polyposis and previous colon adenocarcinoma underwent EGD, which found patchy mucosal abnormalities throughout the duodenum (Figure 1). The polyps were innumerable and coalescent in appearance (Figure 2), and were categorized as duodenal polyposis.

A 58-year-old man taking an over-the-counter herbal laxative containing senna for constipation showed pervasive melanosis coli on colonsocpy. Melanosis coli may be seen in absence of laxative use, such as with topical psoriasis treatments containing anthralin.

The etiology of Chilaiditi syndrome—the transposition of the colon between the diaphragm and the liver—has been associated with chronic lung disease, obesity, and intestinal, liver, and diaphragmatic factors. The characteristics of this patient suggest an episode of acute abdomen due to a cecal volvulus.

A 63-year-old woman presented Henoch-Schönlein purpura and acute esophageal necrosis (AEN), and to our knowledge, there have been no prior reports of AEN associated with Henoch-Schonlein purpura or other vasculitis.

Deglutition syncope is a rare, neurally-mediated syncopal syndrome arising from an aberrant vagotonic reflex
during swallow-associated esophageal dilation. It is highly treatable once identified and multidisciplinary
coordination is helpful in optimizing outcomes and avoiding superfluous testing.

Laparoscopic adjustable gastric band (LAGB) is a surgical device to treat obesity that is widely used and
generally considered to be safe. We report a case of chronic obstruction resulting in marked lower esophageal
thickening 5 years after LAGB placement.

We present a case of squamous dysplasia and early squamous carcinoma of the esophagus after esophagectomy
for esophageal adenocarcinoma. We briefly discuss mucosectomy and ablative therapy as potential treatment
options.

Spontaneous paraesophageal hematoma (SPH) likely shares a common etiology with spontaneous intramural
esophageal hematoma (IEH). We present the first case of a spontaneous paraesophageal hematoma in a patient with hemophilia B.

Ethanol has historically been used as an ablative agent for a variety of lesions, and recent reports have suggested a role for endoscopic alcohol ablation of solid and cystic lesions. We report a novel case of endoscopic ethanol ablation of a peripheral nerve sheath tumor presenting as a small bowel obstruction.

An otherwise healthy 18-year-old man who presented with melena was diagnosed with advanced metastatic testicular choriocarcinoma with evidence of pulmonary, gastric, and brain metastases. Metastatic testicular choriocarcinoma is a rare cause of gastrointestinal bleeding.

We report the first case of acute Vibrio cholerae infection with CT changes consistent with mesenteric panniculitis (MP). In the setting of Vibrio cholerae infection, the CT finding of MP appears to be the result of a immunologically mediated reactive inflammatory disorder of the mesentery.

We report a patient with no prior history of IBD who developed significant bloody diarrhea within 2 weeks of sofosbuvir/simeprevir initiation. Colonoscopy and biopsy confirmed pancolitis, which responded to mesalamine and completion of sofosbuvir/simeprevir.

A man in his sixth decade with Crohn’s colitis and who had been taking infliximab for 18 months tested positive for disseminated Mycobacterium tuberculosis. Clinicians should be aware of the appropriate screening and close monitoring of tuberculosis before and during anti-tumor necrosis factor (TNF) therapy.

Takotsubo cardiomyopathy, also known as left ventricular apical ballooning, broken heart syndrome,
and stress cardiomyopathy, is so named due to its resemblance of a Japanese octopus trap, a tako tsubo. Acute pancreatitis as a trigger for TCM has rarely been reported.

We present a man with a hypoechoic mass in the neck of the gallbladder and the muscularis propria of the duodenum. Examination of the resected gallbladder and perihilar nodes ruled out malignancy and revealed a diffuse inflammatory infiltrate of giant histiocytes with clear, lipid-containing cytoplasm (xanthoma cells), consistent with xanthogranulomatous cholecystitis.

A 56-year-old woman underwent emergent TIPS due to a ruptured esophageal varix during esophagogastroduodenoscopy. Following TIPS, she experienced bilhemia, a rapid rise in serum bilirubin with no evidence of biliary obstruction or hepatic injury. Bilhemia is a rare but serious complication of TIPS.

Eosinophilic liver infiltration is a commonly encountered focal eosinophil-related inflammation with or without
necrosis, which can be seen on CT in the presence of peripheral eosinophilia. Although this entity has a relatively benign course, it is related to numerable conditions for which diagnosis may be challenging.

We present a 29-year-old African American man who presented with jaundice and malaise after starting bupropion and doxycycline. Although both drugs are known to cause liver toxicity, a closer inspection of the signature of liver injury and a review of prior related DILI cases assigns causality more to bupropion than doxycycline.
